Description

Disposable liquid-transfering gun coating gun head and using method thereof
Technical field
The invention belongs to life science/biological field, relate to the concrete technical field of microbiology, molecular biology experiment apparatus and use, relate in particular to a kind of disposable liquid-transfering gun coating gun head and using method thereof for experimental liquid coating.
Background technology
In Microbiology Experiment and molecular biology experiment, the use of spreading rod is comparatively extensive, and as common L-type spreading rod, and common rifle head is also frequent replacing, and consumption is very big.At present dull and stereotyped coating use is spreading rod, and spreading rod material be generally be glass or stainless.
There is very large defect at present such experiment appliance: the drawback of spreading rod own is a lot, must be under the calcination of flame when glass spreading rod uses, and high temperature is easy to grip not, and easily smashes; Stainless spreading rod is because iron and steel specific heat is too little, after heating up heat radiation slowly, meaningless waits for too long, and spreading rod is all coated with and once needs to burn once, uses comparatively trouble.The present invention can overcome above shortcoming, and advantage is: 1, rifle head is removing after sealing shroud, can be bending, and what its original state can possess common rifle head moves liquid function, can be for coating after stretch bending; 2, rifle head can be used as spreading rod, also can move liquid; 3, rifle head is plastic products, disposable, and production prices are cheap, more cost-saving than spreading rod; 4, can autoclaving; 5, in use procedure without flame calcination; 6, a rifle head has substituted rifle head and spreading rod in the past, convenient and simple for operation quick, time saving and energy saving; 7, there is the liquid-transfering gun function of general rifle head; 8, can reduce to drop and the pollution such as spill; 9, be applicable to the every field of liquid extraction coating.10, can support the use with standard liquid-transfering gun rifle, have a wide range of applications field.
In a word, disposable liquid-transfering gun coating gun head easy operating, time saving and energy saving, Painting effect is good, can move liquid and also can be coated with, and sterile working is secure.
